Transition Fit
Transition fit occurs when two toleranced mating parts will sometimes be an
interference fit and sometimes be a clearance fit when assembled.
It may result in either clearance fit or interference fit depending on the actual value of
the individual tolerances of the mating components.
Transition fits are a compromise between clearance and interference fits.
They are used for applications where accurate location is important but either a small
amount of clearance or interference is permissible.
